Small annoyance in the logs, when set to trace.
On the log page of the Openfire Admin tool, selecting “All” on the Lines selector throws an exception, as shown on the same log page.
The functionality still works fine. The log does show a line saying "Will return default value ‘50’ ", but code further down in log.jsp checks for the “All” input text and changes the number of lines to the total if “All” is the value of the ‘lines’ input parameter. See lines 109-150 in log.jsp
Therefore, the only ‘problem’ here is the stack trace in the logging.
